Y TYPEWRITING MACHINE.

Application filedV July 25, 1924. Serial No. 728,075.

rl`his invention relates to gages or devices for locating work-sheets in' a typewriting machine.

In many cases it is desired'ito type only and replace it by a fresh sheetl which is to be typed upon only one 1ineand soon.

OneofI the objects of the present inventionn is to provide'convenient means for adapting the typewriting: machine to different kinds ofY work. For some kinds of work the line of writing, or at least the first line,y necessarily. occupies one position, while in other kinds offwork the first line necessarily occupiesanother position upon the work-sheet. It isusual to provide. a gagefor the endV of a workfsheet, butv much time isV consumed in readjust'mgthe-gage for different kinds of work from time to time.

To overcome this difticu1ty, this invention provides one maingage havingl a certain relation to: the printingy point on the typewriter., so that when the sheet is inserted and placed against said gage, it `will be in a position to receive the first line of` typing thereon, and having. asecond gage between the main gage and the platen',.these gages to lbe used each `to. the exclusion. of the. other, the intermediate gage being .movable out of t-hewaywhenit is desiredvto use the main or remote gage. Hence the machine is readily adjusted for the two kindsk of'work, and it will: only be-necessary to shift the interveninggage into or out of position.

Preferably themain gage is also movable into and outofposition,..the two gagesbeing. preferably mounted on a: single rocking frame5xandin.ordertobring, either gage into use itisonly necessary to rock saidQframe.

Otherl features and; advantages will hereinafter appear. A

Figure G is .a sectional detail view taken von the plane indicated by the line B-B of the printing point, indicated by the type# bar 7 and upwardly. To position the work.; sheet 4 accurately to bring its writingy line 8 (see Figure 7 level with the printing point, it is customary to provide a gage for the work-sheet against which its enditouche-s.- This end gage is shown in the present in'- vention as a pair of"tingei-pieces or stops 9 onV the introductory table 10w'hich islocated to the rear of the plat-en. n

This rear table 10, is hinged at' 121, to the side frames of the carriage.V The table lO'is supported adjustably upon apair of'arnis 12 which are secured to the platen-frame 3 by the screws 13. The slots 14 and the screws 15, operating therein, afford the adjustable connection between the arms 12" and" the table 10; By reason of this construction ,saidv table 10 may be moved up or down to adjust it to the needs of the operator, and

also to true it relatively. to the printing line'.

Mounted securely on the table 10, on one side thereof, and extending substantially its entire length is a side gage 16 made of' metal against which the side edges of the worksheet 4 ride in order to guide the sheet inits vertical' movement. This side gage comprises a flat portion 1T' and an upwardly projecting iiange 1`8.`

rThe single end gage, comprising the fiiigerwpieces or stops 9,.is serviceable when work-sheets with their writing lines occupying the saine position on the sheet are inserted, Uien work-sheets for a different lll hind ot work, having their writing lines located at a diiterent point thereon. are inserted. it would be necessary to readiust this single gage. This would talee considerable time and is diliicult. rlhe present invention eliminates this waste ot time and trouble. This is accomplished by providing a second end gage which is movable into ineliective position when the iirst end gage is used.

This second end gage is located at the rear ot the table 10 and at the point below the lirst end gage. ItI comprises a pair ot brackets l5) secured to the rear ot the table by means ot the screws Q0. li'lountcd to rock in these brackets I9 is a shalit E21 upon which is iixedly mounted trames @n each ot' the trames is secured a metal strip 23 having an angular extension torming a linger-piece or stop 2t. Each of these iingenpieces 2li are directly behind and in alignment with a slot Q5 in the table l0. The linger-pieces Qi are held away trom said slots b v a spring-clip 26 cooperating with the metal strip 23. rlhis spring-clip Q6 is mounted only in the bracket 19 located on the lett side of the table l0. llfhen the uppermost gage is in use the linger-pieces :El are held away trom the slots and behind the table lO by the spring-clip 26. ldlhen the worlesheet for work ot a different character is inserted in the machine and it is necessary to use the second end gage, the linger-pieces Qd may be swung 'forwardly through the slots 25 to the trent oi" the table l() as shown in Figure el. rlhis is accomplished by turning the knob Q7 :fastened to the rock-shaft 21. Vhen the upper end gage is to be used again, the second end gage is swung rearwardly by means ot the knob 27.

While the upper end comprising the linger-pieces i) may be termed on the table 10 as shown, it is preferred that this gage also be movable into and out ot ellective position. This is accomplished as shown in Figure 3, wherein the metal strip E23 is en tended and terminates in a lingenpieee or stop 2S similar to the linger-piece 2li. Thus the two end gages may be stamped troni a single piece ot metal. The linger-piece 28 is located directly behind and in :'ilignment with the slot Ql in the table lil. By reason o t this constriu-tiim, when the knob 2T is turned to swing the linger-piece 28 through the slot Q9 into etieetive position, the lower `finger-piece 2l .is siinultaneiiusly swung rearwardly out ot eii'eetive position. Then either oi said gages is swung into ellective position it is held there by the springelip 2G.

`While only a main gage and an intermediate gage are illustrated and described, it is obvious that two or more intermediate gages might be provided to give the machine a greater range ot adaptabilitji.

neeasae Variations may be resorted to within the scope oi the invention, and portions ott the improvements may be used without others.

l-laving thus described my invention, I claim:
